Chris DiFonzo just notified me that she has found soybean aphids on early planted soybeans in Michigan. This is a very good indication that Ontario could have aphids on any soys that have emerged. Try to get out and scout fields between the rains this week. If anyone finds fields with aphids in them, please notify me as we are trying to set up some field trials on these early season infestations.
